Secrets

 * 1) The area holding the red skullkey to the right of where you start also holds a secret in one of the compartments housing imps. Once you've cleared the enemies, use the platform to go up and press the switch to cause several platforms to show up in the center. Then, make your way to the first imp compartment that was in front of the switch, then immediately dart to the compartment opposite it where a hidden room containing a BFG9000 will briefly have lowered. (sector 307)
 * 2) See secret #1 (thing 199)
 * 3) After picking up the blue skullkey, go to the left where a door will have opened to reveal a set of stairs, and press the misaligned wall on the right to find an energy cell pack. (thing 359)
 * 4) Upon obtaining the yellow skullkey, several doors behind you will open to reveal many lost souls. Enter these rooms to find a hidden invulnerability sphere. (thing 237)
